Title: Method of neutron logging and a deviice for the realization of the method
Inventor: KULYK VOLODYMYR VASYLIOVYCH
Filed: 2000-11-24
Abstract: The present invention can be used for investigating wells in geological prospecting of oil, gas, and ore deposits as well as in hydrological investigations. The proposed method of neutron logging consists in recording, in the investigation process, in identical conditions, slow and above-thermal neutrons derived from the interaction of the neutrons, which are generated by a neutron radiation source, with a rock. Using a computer system for data processing and analysis, the difference of the recording rates for above-thermal and slow neutrons is determined. The said rate difference, which constitutes the recording rate for thermal neutrons, is used for determining parameters that characterize absorption of neutrons in the investigated medium. A device for the realization of the method contains a slow neutron detector and an above-thermal neutron detector, which are installed symmetrically relative to a neutron radiation source, and a computer system for data processing and analysis. The outputs of the said detectors are connected to the inputs of the computer system. The present invention provides for improving classification of rocks according to their ability of neutron absorption and increasing accuracy and sensitivity in determining concentrations of anomalous thermal neutron absorbers.
